Gravitational wave detection with photometric surveys [PDF]
Physical Review D, 2020 Gravitational wave (GW) detections have considerably enriched our understanding of the universe. To date, all the known events were observed via direct detection.

Exploring the Impact of Microlensing on Gravitational Wave Signals: Biases, Population Characteristics, and Prospects for Detection [PDF]
, 2023 In this study, we investigate the impact of microlensing on gravitational wave (GW) signals in the LIGO$-$Virgo sensitivity band. Microlensing caused by an isolated point lens, with (redshifted) mass ranging from $M_\mathrm{Lz}\in(1,10^5){\rm M}_\odot ...

Advances in Astronomy, Volume 2014, Issue 1, 2014., 2014 The perturbation caused by planet‐moon binarity on the time‐of‐arrival (TOA) signal of a pulsar with an orbiting planet is derived for the case of the orbit of the planet‐moon system inclined of an angle α with respect to the plane of the orbit of the planet‐moon barycenter around the pulsar.

Probing the Spatial Distribution of Extrasolar Planets with Gravitational Microlensing [PDF]
, 2003 To search for extrasolar planets, current microlensing follow-up experiments are monitoring events caused by stellar-mass lenses, hoping to detect the planet's signature of the short-duration perturbation in the smooth lensing light curve of the primary.

Exoplanet Detection Techniques [PDF]
, 2014 We are still in the early days of exoplanet discovery. Astronomers are beginning to model the atmospheres and interiors of exoplanets and have developed a deeper understanding of processes of planet formation and evolution.

Robotic Astronomy with the Faulkes Telescopes and Las Cumbres Observatory Global Telescope
Advances in Astronomy, Volume 2010, Issue 1, 2010., 2010 We present results from ongoing science projects conducted by members of the Faulkes Telescope (FT) team and Las Cumbres Observatory Global Telescope (LCOGT). Many of these projects incorporate observations carried out and analysed by FT users, comprising amateur astronomers and schools.

Free-floating Planet Mass Function from MOA-II 9 yr Survey toward the Galactic Bulge
The Astronomical Journal, 2023 We present the first measurement of the mass function of free-floating planets (FFPs), or very wide orbit planets down to an Earth mass, from the MOA-II microlensing survey in 2006–2014.

Confirmation of Color-dependent Centroid Shift Measured After 1.8 Years with HST
The Astronomical Journal, 2023 We measured the precise masses of the host and planet in the OGLE-2003-BLG-235 system, when the lens and source were resolving, with 2018 Keck high resolution images.

Exoplanets - search methods, discoveries, and prospects for astrobiology [PDF]
, 2008 Whereas the Solar System has Mars and Europa as the best candidates for finding fossil/extant life as we know it - based on complex carbon compounds and liquid water - the 263 (non-pulsar) planetary systems around other stars as known at 15 September ...
